Commercial Water Heater Maintenance Best Practices

Extend the life of your water heating system and avoid unexpected failures with these maintenance tips.

Commercial water heaters are critical for daily operations, yet they're often overlooked until they fail. Proper maintenance can extend equipment life by 5-10 years and prevent costly emergency replacements.

Monthly Maintenance Tasks

  • Check for leaks around connections and valves
  • Monitor water temperature settings
  • Inspect pressure relief valve
  • Check for unusual noises or vibrations

Quarterly Maintenance

  • Flush sediment from tank (critical for hard water areas)
  • Test pressure relief valve operation
  • Inspect anode rod (replace if more than 50% depleted)
  • Check burner assembly and flame (gas units)
  • Inspect electrical connections (electric units)

Annual Service

  • Complete system inspection
  • Efficiency testing
  • Component replacement as needed
  • Water quality testing
  • Safety system verification

Common Issues and Prevention

Sediment Buildup

Hard water areas require more frequent flushing. Sediment reduces efficiency and can cause premature failure.

Anode Rod Depletion

The anode rod protects the tank from corrosion. Check annually and replace when needed to extend tank life.

Temperature Issues

Maintain temperature between 120-140°F. Too low risks bacterial growth; too high wastes energy and creates scalding hazards.

Signs of Problems

  • Inconsistent water temperature
  • Rusty or discolored water
  • Unusual noises (popping, rumbling)
  • Leaks or water around unit
  • Increased energy bills

When to Replace

Consider replacement if your water heater is:

  • More than 10-15 years old
  • Requiring frequent repairs
  • Not meeting hot water demands
  • Showing signs of tank failure (leaks, rust)

Regular maintenance is the key to reliable hot water service. Partner with a maintenance provider to ensure your system receives proper care.
